Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner flame stabilizer. Background Technology

[0002] In the field of burner technology, the flame stabilizer, as a key component of the burner, primarily functions to stabilize the flame and promote thorough mixing of fuel and air. However, traditional flame stabilizer designs have some shortcomings. On the one hand, many flame stabilizers employ a planar vane structure, which, while achieving flame stabilization to some extent, is difficult to effectively adjust and optimize due to space constraints in burner installation. On the other hand, existing flame stabilizers are insufficient in their fuel-air mixing. Some flame stabilizers have fixed swirl vane angles, which cannot be adjusted according to different combustion conditions and fuel characteristics, resulting in uneven fuel-air mixing, low combustion efficiency, and increased pollutant emissions. Furthermore, some flame stabilizers fail to fully consider the synergistic effect between the fuel injection port and the swirl vanes, affecting the initial fuel injection velocity and diffusion range, further limiting the improvement of combustion performance.

[0003] Therefore, a burner flame stabilizer is proposed to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-3 As shown, the present invention provides a flame stabilizer for a burner, comprising a flame stabilizer 1 and a guide frame 2. The flame stabilizer 1 includes swirl vanes 11 and a flame-damping section 12. The swirl vanes 11 are evenly spaced and circumferentially distributed on the front side of the flame-damping section 12, and the guide frame 2 is installed on the back side of the flame-damping section 12.

[0022] By adopting the above technical solution, a uniform swirling effect is generated, which allows the fuel and air to mix fully, improves combustion efficiency, and enhances flame stability, preventing flame backfire or flame lift-off.

[0023] The air deflector 2 can guide the airflow, making it more evenly distributed, further promoting the mixing of fuel and air, and improving the uniformity and stability of combustion.

[0024] The guide frame 2 includes a support part 21 and a connecting part 22. The support part 21 is installed at the end of the connecting part 22, and the connecting part 22 is connected to the flame arrestor part 12 by a stud.

[0025] By adopting the above technical solutions, the stability of the flame stabilizer is ensured under harsh working environments such as high temperature and high pressure, and its service life is extended.

[0026] The support part 21 includes support blades 211, which are evenly distributed on the outer side of the center, and the number of support blades 211 is 3.

[0027] By adopting the above technical solution, the support blade 211 increases the structural strength of the guide frame 2, preventing it from deforming or being damaged under the impact of airflow, which helps to further guide the airflow and optimize the combustion process.

[0028] The connecting part 22 includes guide vanes 221 and a connecting ring 222. The guide vanes 221 are evenly distributed on the outside of the connecting ring 222, and the number of guide vanes 221 is 3. The connecting ring 222 is connected to the flame arrestor part 12.

[0029] By adopting the above technical solution, the guide vane 221 pre-swirls the airflow, so that it can better match the swirling flow generated by the swirl vane 11, improve the mixing effect of fuel and air, and further improve the combustion efficiency.

[0030] The connecting ring 222 has a hollowed-out part 2221 in the middle, and the hollowed-out part 2221 is directly opposite the center of the flame stabilizer 1.

[0031] By adopting the above technical solution, the hollow part 2221 provides a direct airflow channel for the fuel injection port 14, so that the fuel can be injected more smoothly into the combustion zone, mix with the air quickly and burn.

[0032] The flame stabilizer plate 1 also includes flame stabilizing holes 13, which are evenly spaced and circumferentially distributed on the flame-blocking part 12. The position and number of the flame stabilizing holes 13 are consistent with those of the swirl plate 11.

[0033] By adopting the above technical solution, the flame stabilizing hole 13 can guide part of the fuel and air to mix and enter the combustion zone, forming a stable flame core and enhancing the stability of the flame.

[0034] The flame stabilizer 1 also includes a fuel injection port 14, which is located in the center of the flame stabilizer 1 and is connected to the flame stabilizing hole 13.

[0035] By adopting the above technical solution, the fuel is concentrated in the central area and interacts with the swirling airflow generated by the swirl vane 11 and the guide vane 221 to achieve a more uniform fuel distribution and more complete combustion.

[0036] In a specific implementation of this utility model, fuel is injected into the center of the flame stabilizer plate 1 through the fuel injection port 14. The fuel injection port 14 is connected to the flame stabilizer hole 13, and the fuel forms a concentrated injection in the central area.

[0037] Combustion air enters from the periphery of the flame stabilizer 1 and is diverted by the flame stabilizer 1. Part of the air is directly ejected through the flame stabilizer hole 13 to form a high-pressure airflow; the other part of the air flows out through the swirl channel of the swirl vane 11.

[0038] The air passing through the swirl vane 11 is guided by the swirl channel to form a swirling airflow on the surface of the flame stabilizer 1;

[0039] The high-pressure airflow ejected through the flame stabilizing hole 13 mixes with the swirling airflow on the surface of the flame stabilizing disk 1, and is fully mixed with the fuel in the combustion zone to form a stable flame. The support blade 211 and the guide blade 221 maintain the stability of the flame and prevent the flame from backfired or leaving the flame.

[0040] By rotating the screw, the flame stabilizer 1 moves back and forth on the screw, thereby adjusting the distance between the flame stabilizer 1 and the outer nozzle, thus changing the airflow and optimizing the combustion effect.

[0041] The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
